Peggy Olson (Elisabeth Moss) in Season 4 of "Mad Men."
"Peggy has changed the most of any character on the show." Tom says of the secretary who has worked her way up the "Mad Men" ladder.
"The wardrobe Janie has picked for her reflects that."

Earlier in the show's run Peggy's costumes were defined by school girl separates and prim styling.
"The character is so much like Don Draper," Tom says of Draper's onetime protege. "Even with the infidelity."
The move away from "girlish" fashion has told that character's story as much as any plot line from the last six season.

"Yellow and orange are going to be huge this season," Tom says. "They're moving to California, and the wardrobe will be sunnier, too." Color schemes have frequently given fans of the show much room for discussion and interpretation.
"I don't think they sit down and say 'orange' means this and 'yellow' means that," Tom says, "but they're at least subconsciously telling you something about the story."

Season 5 of "Mad Men" saw Peggy move away from her modest (and occasionally dumpy) silhouettes of seasons past but details like the Peter Pan collar show she hasn't entirely given up playing the juvenile.
"Part of Peggy's story has always been that Matthew Weiner based her partially on his mother," Tom points out.
"We'll see where that goes," Lorenzo laughs.

Peggy, seen here with "Mad Men" cast members (from left) Christina Hendricks, John Slattery, Jared Harris, Vincent Kartheiser, Jon Hamm, Robert and Robert Morse in the fifth season, has never entirely fit in with either the men or the women of the agency.
"She's unlike all the women on the show," Tom points out. "Betty was sort of a Grace Kelly until she got fat and dyed her hair, now she's Grace Kelly again. Joan is obviously the Marilyn Monroe and Megan is vaguely Sharon Tate styled. Peggy doesn't have a box she fits into. Don is the person on the show she's probably the most like."

Peggy's brief affair with Ted Chaough (right, played by Kevin Rahm) promises to continue to cast a shadow over season seven.
As Peggy rises in the ad world her style continues to get more sophisticated.
"Janey has really kept the costumes true to the spirit of the decade," Tom and Lorenzo agree. "She looks to the real people of the era."

Although Peggy will never have the "va-va-voom" (in Tom's words) wardrobe of a Joan as the character has become more sexually liberated her clothes have started to tip their toes toward being slightly more provocative. This red dress from season six is a nice transitional piece between the two Peggys.

"California is going to affect the story and the clothes hugely in the new season," Tom and Lorenzo agree.
